• Support window groups, both as defined by applications, and defined by the user (either interactively through the window's menu, or via the auto-group-alist and persistent-group-ids variables).

  For most commands working on single windows, there's also one operating on the group that the current window is a member of. (With the notable exception currently of moving windows.) There's also options controlling whether (de)iconification operates on windows or groups
